2 Claims.

This invention relates to electric fans and more particularly to fansfor outdoor use and has for its objective the provision of an improvedsupport for the fan, and improved means for clamping the fan to thesupport.

The invention will be readily understood from the following detaileddescription in connection with the accompanying drawings, in which:

Figure 1 is a perspective View of the fan and its support.

Figure 2 is a fragmentary view of the support and the means for clampingthe fan to the support, the clamping means and part of the support beingshown in section.

Figure 3 is a rear elevation of the clamping means and the horizontaltube to which the motor is clamped.

In the selected embodiment Ill represents a square shaped base havingone end of each of the inclined bars II and I2 welded thereto at itscorners. The upper ends of the bars I2 are welded to the bars H and ahorizontal rod in the form of a tube I3 is supported by the upper endsof the bars I I.

The fan motor I4 which drives the blade I5 is carried by the plate IE,to which it is secured by the bolts H. The plate I6 is formed with twodownwardly extending ears I8 which are apertured to receive thehorizontal tube I3. To frictionally hold the fan in its adjustedposition relative to its base I have provided two blocks 20 and 2| whichare located on opposite sides of the rod or tube l3 and each is formedwith a chamfered surface 23 which engages the rod l3, and a flat face 24which engages the under side of the plate IS.

The blocks 20 and 2| are apertured to receive a bolt 25 which extendsthrough the blocks. The blocks are adapted to be drawn together by thenut 26 threaded on the bolt 25. A lock-nut 21 is provided to lock thenut 26 in position. From the above it will be observed that the nuts 26and 2'! may be loosened to permit the blocks to separate slightly andthe fan and its base adjusted to different angular positions about thetube I 3. The nuts may then be tightened to lock the fan in its adjustedposition.

To limit the swinging movement of the fan and its base about the tube I3a lug 28 is welded to the tube I3 and the ends of the lugs are arrangedto be engaged by either the block 20 or 2|. Lugs 29 are also provided toprevent the cars from shifting laterally on the tube I3.

The fan is particularly adapted for cooling transformers and is used outof doors. Its angular position is usually adjusted so that the fan isdirected upwardly, its normal position being substantially as indicatedin dotted lines in Figure 2. It will be seen from Figure 2 that the earsI8 are attached to one end of the plate I6 so that when the fan is inits normal position its center of gravity is in a vertical planeintersecting the tube I3. This construction reduces the tendency of thefan to turn about the tube I3 as a pivot. Holders 30, are fixed to thebars I2 about which the electrical conductor cord may be wound when thefan is being transported from place to place.

Having thus set forth the nature of the invention, what I claim hereinis:

1. A support for an electric fan comprising a base, a horizontallydisposed rod supported by said base, a supporting plate having dependingmembers which embrace said rod, blocks interposed between said rod andsaid plate and having faces in contact with the rod and plate, means foradjusting said blocks to cause them to grip the rod and prevent theplate from turning on said rod, and a stop lug carried by said rod andin position to be engaged by either of said blocks for limiting themovement of said plate relative to said rod.

2. A support for an electric fan comprising a base, a horizontal rodsupported by said base, a supporting plate formed with depending earswhich are apertured to receive said rod, a pair of blocks interposedbetween said rod and said plate, each of said blocks having a chamfered.

surface which engages the rod, adjusting means extending through saidblocks for the purpose of drawing said blocks together to cause thechamfered surface on the blocks to frictionally engage said rod, a stopfixed to said rod for limiting the movement of said plate about thelongitudinal axis of the rod and stop lugs fixed to said rod andcooperating with the depending ears formed on the plate for preventinglateral shifting movement of said plate relative to said rod.
